To all whom it may concern:

Be it known that I, JOHN ANNAU, citizen of Austria-Hungary, residing at Morrell Park, Baltimore, in the State of Maryland, have invented certain new and useful Imi rovements in Water-Heaters for Bathubs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to water heaters for bath tubs, and one of the principal objects of the invention is to provide a heater connected to the bath tub for circulating the water from the bath tub through the heater and back again, said heater being preferably of the type requiring such fuel as charcoal.

Another object of the invention is to provide a water heater connected to a bath tub comprising a water jacket with a series of circulating pipes, and means for heating the water in the clrculating ipes, and discharging their contents back into the bath tub.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawings, in

which- Figure 1 is a top plan view of a bath tub provided with a heater made in accordance with this invention, Fig. 2 is a longitudinal sectional view through the heater and through a. portion of the bath tub, Fig. 3 is a transverse vertical section of the heater, and Fig. 4 is a vertical section through the detachable heater.

Referring to the drawings, the numeral 1 designates a bath tub which may be of the usual or any suitable type or construction, and connected to the foot of the bath tub is a heater comprising an outer casing 2, an inner casing 3, and water pipes or fines 4, extending across the heater and communicating with a water jacket 5. The heater is connected to the bath tub by the upper head 6 and the lower head 7. Underneath the heater is an ash pan 8, adapted to slide in guide ways 9 connected underneath the heater.

The waste pipe 11 connected to the bottom of the bath tub is provided with an overflow pipe 12 which communicates with the waste pipe 11 below the bath tub and extends up to the desired water line in the tub. The

The bath tub is provided with openings 10 leading into the water jacket 5. L

pipes 4 serve as grates for receiving fuel such as charcoal for heating the water jacket 5 for circulating the water through the pipes 4 back into the bath tub.

A heating casing 13, having its upper end closed by a top wall and a downwardly depending flange 14 formed on its lower end to be received in the upper end of the casing 3, is provided whereby the heat from the fire within the casing 13 will heat the room. A suitable door is mounted in the side of the casing 13, whereby fuel may be set into the casing 13 for feeding the fire, and a suitable smoke stack 16 is carried by the opposite side of the casing to allow smoke and fumes to be conveyed from the casings 3 and 13.

From the foregoing it will be obvious that a water heater made in accordance with this invention may be employed for heating the water in bath tubs in places where there are no especial water heating devices, or in the summer time when it is not desired to build a fire in the furnace for heating the bath water.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined in the claims.

What is claimed is:

1. In combination with a bath tub having openings in one end thereof, of a heater comprising ufpper and lower heads secured to the end 0 the bath tub and having openings therein, an outer casing secured to said heads and the bath tub, an inner casing extending through the openings of the heads and having its ends bent to engage the faces of the heads to form a water jacket to receive water from the bath tub, water pipes extending transversely of the inner casing and in communication with the water jacket, said pipes forming a grate to support a fire for heating the water in the water jacketto set up a circulation of water therein and in the bath tub, and an ash tray connected to the lower head and positioned under the inner casing to receive ashes from the fire.

2. In combination with a bath tub having openings in the end thereof, of a heater comprising an outer casing, upper and lower heads secured to the casing and to the tub and provided with openings therein, an inner casing mounted in said heads to form a water jacket, water pipes carried by said upper end of the inner casing to receive heat the fire within the inner casing for a door carried by the heat for supplying fuel to the from heat ng a room, receiving casing fire, and a smoke stack connected to said last named cnsin In testimony w iereof I ufiix my signature in presence 0 two witnesses.
